Flower morphological characteristics influence abundance and foraging behavior of pollinators. As a source of food, nectar has important role in attracting pollinators and improving the percentage of fertilization in sunflower. On the other side, presence and density of capitate glandular trichomes in the area of anthers, which produce mainly sesquiterpene lactones and flavonoids, is frequently associated with protection against herbivores and pathogens. Therefore, for detailed understanding of the attractiveness of capitula to insects, secretory tissues of disc flowers in wild sunflower species were investigated. Stereoscopic, light and scanning electron microscopy were used to examine nectary anatomy of 21 wild Helianthus species. Presence and distribution of capitate glandular trichomes were analyzed on the same flowers in the anther region. In all analyzed species nectaries are ring shaped and located above the inferior ovary. The nectary is composed of two distinct tissues: the ep...idermis (single cell layer with modified stoma) and 5-8 layers of secretory parenchyma cells located subepidermally
